If you want to see more of Black Panther, you'll have your chance next month, as he'll reappear in Marvel/Disney’s next superhero tentpole Avengers: Infinity War. A new trailer dropped today (March 16) and it has fans crying and worried— in a good way.

Infinity War is, arguably, one of the biggest Marvel flicks ever made with every single superhero in the MCU appearing in it, including Iron Man, Black Panther, Thor and Captain America, just to name a few. As the new star-studded trailer shows, it looks like T’Challa and the Wakandans, along with the Avengers have to battle their biggest and fearsome adversary yet in Thanos (played by Josh Brolin).

Thanos promises death and destruction as he collects precious Infinity Stones from every superhero. “The entire time I knew him, he only ever had one goal: to wipe out half the universe. If he gets all the Infinity Stones, he can do it with the snap of his fingers,” says Zoe Saldana’s character Gamora.

Fans on Twitter expressed their concern over the fate of their favorite superhero. Apparently, in the comic book series, Captain America dies at the hand of Thanos. In the trailer, we see Captain America face off with Thanos and it doesn’t look good for Marvel’s patriotic hero.

Other comic book nerds are worried that Thanos might take over Wakanda for their sought-after Vibranium. Others are also speculating that a new Marvel superhero will be introduced in the film.

Overall, fans are biting their nails in anticipation for the release of Avengers: Infinity War, which hits theaters on April 27.
